The centimeter per hour (cm/h) is a unit of measurement for velocity, indicating how many centimeters an object travels in one hour. This metric is particularly useful in fields such as physics, engineering, and transportation, where precise measurements of speed are essential.
The centimeter per hour is part of the metric system, which is standardized globally. It is derived from the base unit of length, the meter, where 1 centimeter equals 0.01 meters. The hour is a standard unit of time, making cm/h a reliable measure for speed in various applications.
The centimeter as a unit of length was introduced in the late 18th century as part of the metric system, which aimed to provide a universal standard for measurements. Over time, the centimeter per hour has evolved to become a practical unit for measuring slow speeds, particularly in scientific experiments and certain industrial processes.
To illustrate how to convert kilometers per hour (km/h) to centimeters per hour (cm/h), consider a vehicle traveling at a speed of 60 km/h.
This example highlights how the centimeter per hour can be used to express speeds that may otherwise seem abstract in larger units.
The centimeter per hour is commonly used in various applications, including:

The Mach unit, represented by the symbol M, is a dimensionless measure of speed defined as the ratio of the speed of an object to the speed of sound in the surrounding medium. It is a crucial metric in fields such as aerodynamics, aerospace engineering, and fluid dynamics, where understanding the relationship between an object's speed and the speed of sound is essential.
Mach is standardized based on the speed of sound, which varies with temperature and pressure. At sea level and at a temperature of 20 degrees Celsius, the speed of sound is approximately 343 meters per second (1,125 feet per second). The Mach number is calculated by dividing the speed of the object by this standard speed of sound.
The concept of Mach was introduced by the Austrian physicist Ernst Mach in the late 19th century. His work on shock waves and supersonic speeds laid the foundation for modern aerodynamics. Over the years, the Mach number has become a fundamental parameter in the design and analysis of aircraft and rockets, enabling engineers to predict performance and behavior at various speeds.
To illustrate the use of the Mach number, consider an aircraft traveling at a speed of 680 miles per hour. To convert this speed to Mach, we first convert miles per hour to meters per second (1 mph ≈ 0.44704 m/s):
680 mph ≈ 303.9 m/s.
Next, we divide the speed of the aircraft by the speed of sound at sea level:
Mach = Speed of Aircraft / Speed of Sound = 303.9 m/s / 343 m/s ≈ 0.886 M.
Thus, the aircraft is traveling at approximately 0.886 Mach.
The Mach number is widely used in various applications, including:
To use the Mach Converter Tool, follow these simple steps:
What is the Mach number? The Mach number is a dimensionless unit that represents the ratio of an object's speed to the speed of sound in the surrounding medium.
How do I convert miles per hour to Mach? To convert miles per hour to Mach, divide the speed in mph by the speed of sound at the given conditions (approximately 343 m/s at sea level).
Why is the Mach number important in aviation? The Mach number helps engineers and pilots understand an aircraft's performance relative to the speed of sound, which is critical for safety and efficiency.
Can I use the Mach Converter Tool for different units of speed? Yes, our Mach Converter Tool allows you to convert various units of speed, including kilometers per hour and meters per second, to Mach.
What factors affect the speed of sound? The speed of sound is influenced by temperature, pressure, and the medium through which it travels (e.g., air, water).
